For years OnePlus has been proud with its speed even for a long term use. It is powered by Snapdragon 855 chipset paired with either 6,8 or 12GB RAM. The speed is also matched by OxygenOS, OnePlus’ UI on top of Android. The big upgrade here compared with the OnePlus 6T is the screen. We have a 6.67-inch display which is bigger plus its an AMOLED panel and has refresh rate of 90Hz which perfect for intense gaming.
